Why do we need a trigger warning you ask? Because the mere idea of FFMS2 being updated is a big shock to most people? No. In fact it was caused by me once again declaring that XP is a dead end. This time using slightly different wording. If you meet any of these unfortunate users in real life don’t tell them that XP support ended long ago. They may go on a violent rampage or even worse, be offended.

Also a pile of bugs got fixed but nobody actually cares about that, after all we’ve now got a controversy surrounding this release and that’s more interesting.

Look at this image and remember the good old times that were actually shit

I actually did test this release. I mean it. Not like the previous one where only the core parts got tested. Anyway, this release fixes all known regressions that appeared in R33 and optimizes several internal functions. It also adds support for handling pre-multiplied alpha in MaskedMerge and a PreMultiply filter to apply it.

VSFS was removed and replaced with AVFS, importing all improvements such as faster mount speed and other fixes. The codebase was also unified for both Avisynth and VapourSynth to make maintaining it less annoying in the future. But wait! There’s more! When using recent Avisynth+ builds it can now output exactly the same high bitdepth formats as VapourSynth! Interestingly this makes AVFS considerably better than the current VFW output of Avisynth+.

Possibly breaking changes:

Temporalsoften plugin no longer included because it’s horrible, use FrameAverage from miscfilter instead
